Best pump out there!

I LOVE my willow pump. Before purchasing I asked a few friends if they liked theirs everyone said there’s a learning curve transitioning from another pump to the willow. I decided to use my willow before any other electric pump and I found it rather simple to use! I bought the pump when they first released the containers. I had a few issues always getting an error message that the parts weren’t connected right. After getting help from the support team, it turns out I just needed to clean out the valves more thoroughly! They were super helpful and it works perfectly since! I recommend this pump for all my mama and mama to be friends! I love being able to move around and how discrete you can be (wearing some baggy clothes on top) while pumping!

Great product

Frankly I haven’t had any issues with this pump. It worked from the start on my first try with great results. I respond well to it even on the lowest setting so I haven’t even had to try increasing the intensity. It has definitely been a game changer for me with a full time job, a toddler, a newborn and a husband that is away for work often. I was only able to breastfeed for 7 months (plus a 2 month freezer stockpile) with my first because of the demands on my schedule but Willow has made a huge difference this time around and I have no doubt I will get to the one year mark and beyond. The containers are amazing too.

The best thing ever

The Willow Pump has really made pumping easier, with my first kid i dreaded pumping, sitting there for 20-40 min at a time was sometimes quite difficult when you have to care for newborn as well. After making the decision to purchase Willow pump with my second, it made it a lot easier for me to pump on schedule and clean and care for baby all while pumping ! I must admit tho it was difficult to get the right alignment, I almost gave up on the pump but kept trying cause of how convenient it was. After you get use to it, it’s very easy to use.

2nd baby, first time BF, successful bc of Willow!

First babe wasn’t successful with BF the “classic” pump I used kept me tied to one spot, a million pieces. I wanted to BF this time and I wanted to be successful. My insurance reimbursed $180 of any pump I bought. I used my HSA to pay for the rest. I also bought an extra charger and the containers too. I chose the willow after reading many reviews and blogs. I am so so thankful for the pump. They work so well. I can move freely and the parts are quick to assemble and easy to clean. I have both the containers and the bags. I like the bags better. My HSA continues to pay for the bags as I need them. My advise to the new willow moms is watch the videos on the app. Super helpful! 2 months and counting. I’ve never been so proud.

The pump for moms who hate pumping!

Just had my third child and I did not look forward to pumping milk. Saw this pump on Instagram and thought it was too good to be true...but it wasn’t! I can pump anytime and anywhere! Do chores, play with my kids...heck, I can even pump and feed my baby at the same time!! Pumping is no longer a stressful chore. I would recommend moms to buy the milk containers and use your own milk bags to save money.
